oh dude, I have a HUGE database of halo sprites, i'll upload them for you in a minute!

Here you go: http://www.savefile.com/files/1039279

this has sprtes of all the halo weapons, grunt sprites, heritic grunt sprites, and a HUGE data base of master cheif sprites (which are WAY better than your current ones, no offence). They even have sprites of master chief holding every weapon and running animations for each weapon so you can make a game out of them!!!
